An α-particles travels a well-defined distance before coming to rest. This distance is known as the range of the particle. The range depends upon:
Correct answer: D. All of these
- A. Charge of the particle
- B. Mass of the particle
- C. Energy of the particle
- D. All of these
Explanation
An α-particle travels a well defined distance in a medium before coming to rest. This distance is called the range of the particle. The range depends on the:i. charge, mass and energy of particleⅱ. The density of the medium and ionization potential of the atoms of the medium.

About Nuclear Physics
Atomic nuclei contain protons and neutrons, with nuclear size, mass defect and binding energy describing their stability. The work covers alpha, beta and gamma decay, decay equations, half-life and decay rate, along with radiation safety and medical applications such as imaging, radiotherapy and tracers.
